High Tech Turbo- S300G Stage 2 Upgrade*- 1994-2002 Dodge Cummins 5.9 12/24V
Anyone tried this? I called HTT yesterday about it, they told me it's a 60mm inducer, but the guy wasn't sure if it was extended tip or any of that. Says it won't add lag to a point that one could notice it...bolts on, no issues reported with balance that they've heard of. The link I gave is the cheapest I've seen it, which is far cheaper than HTT's website. I have a standard 174430 S300G brand new, going into a twin set with a Batmo K31 (71/86/1.28 gated) and was thinking of adding the bigger compressor to the G.
Originally, I was going to use my A3K and switch the 14cm gated S300 housing onto it, but ATS cuts the exhaust end of the CHRA housing about 1/4" smaller to fit into the .85 A/R non-gated housing. Too bad cuz the A3K compressor cover looks like it flows much better than the S300G cover. I thought about changing the A3K compressor wheel and cover over to the S300, but I thought it may be a better option to sell the A3K, buy the 60mm upgrade and have some cash left over.
Or I may just run it as is, unless someone can tell me the HTT upgrade is totally awesome. PS. searching keeps giving me matches to 60mm compressor upgrades for the Holset turbos.
PPS. if anyone has or is getting a twin set up from PDR, a Steed Speed manifold does NOT work with it! It sticks out too far and won't allow the hotpipe to swivel as close to the block as the ATS manifold does. This puts the downpipe outlet straight into the firewall. I had to remove everything again to re-use the ATS manifold and am in the process of getting more manifold gaskets, since I torqued down the ones I had with the Steed Speed. The truck is an hour drive from here at my Uncle's farm, I live in an apartment, which is no good for big installs. I'll try to do the thread on the twins once they're in for good.
OK, I'm rambling, HTT upgrade - good or bad?
